Excuse me, how did you shoot the shells under the ultra-high-speed camera?

Be sure to design a set of things specially for this shoot.

It is said that a French photographer spent more than one million francs to photograph the take-off of an aircraft carrier.

The beginning of this incident is linked with the shooting of guns. When the shell flies out, the camera just starts and rotates at a pre-designed speed to track the shell. (The speed of the shell is known)

In order to ensure the clarity of the projectile, the focus must be set in advance, and the focus has a far-near-far changing process. In order to ensure accurate exposure (because the muzzle flash is far brighter than the grass), a set of exposure program must be designed, which may be controlled by a computer, and the aperture will gradually expand according to the change of the exit time.

It's definitely not a single shot. You always have to try several times and gradually improve the shooting software and hardware to succeed. Absolutely expensive.
